Form#importSchema(schema: Schema, data?: Data) => Promise<Result, Error>

Display a form represented via a form schema and the optional data.

  await form.importSchema(schema);
} catch (err) {
  console.log('importing form failed', err);
}

Form#submit() => { data: Data, errors: Errors }

Submit a form programatically.

const {
  data,
  errors
} = form.submit();

if (Object.keys(errors).length) {
  console.error('Form submitted with errors', errors);
}

Form#validate() => Errors

Validate a form programatically.

const errors = form.validate();

if (Object.keys(errors).length) {
  console.error('Form has errors', errors);
}
